I have had hip and back problems most of my life and have slept on latex foam mattresses which have helped. This mattress looked like a burrito when it arrived but once out of the box and plastic wrapper it shaped up nicely. I didn't notice any smell at all. It took about 7-10 days for it to arrive but it was well worth waiting for and priced right for my budget. I don't notice too much difference in the cool max cover but then I have a mattress pad under my sheets to protect it. I want this bed to last me a really long time. I never feel achy or stiff when I get up in the morning now. It was definately a good investment!
